Make your Solar Count !

We are using factors like panel specifications, location, age and your state's electricity grid mix to determine how much CO2-intensive grid electricity you're avoiding.

CO2 Saving Formula: Annual system performance  ×  Local grid carbon intensity - Embodied emissions

Example: 5,500 kWh pa x  0.6 T ÷ kWh [60% fossil] - 0.3 Tonnes = 3 Tonnes CO2

We certify your solar CO2 savings using a retrospective, evidence-based approach focused on actual household solar generation and grid emissions displaced.

From a data collection, we will request the following: 

• Period: Last 12 months generation (eg. 5,500 kWh)
• Source: Either Inverters, Monitoring app or Smart Meter
• Format: Visual evidence (photo, app screenshot, video) or Solar App data feed

Aetium’s solar CO2 savings are based on real data and robust science to ensure accurate, location-specific and verifiable results. The calculation datasets include:

• Sunlight & Climate (CSIRO, Solargis, BOM).
• System Performance (NREL, IEEE, academic studies),
• Grid Standards (AEMO,  Ausgrid, Ergon),
• Household Energy use (CSIRO, ABS),
• Carbon Accounting (AEMO, NGER, LCA research).

Input data and calculations are undergoing periodic review to ensure that our carbon certifications are of the highest integrity.

• Once certified, you will be allocated TCUs that represent exactly how much CO2 was avoided by your solar.
• You can sell your TCUs on the Aetium Exchange.
• The AUD value of the TCUs will be transferred to your bank account net of our service fee.

Yes, as an assessable income for individuals and attract GST for businesses.

Aetium’s current research indicates that STCs are not officially classified as carbon offsets.

Aetium is currently seeking formal clarification from the Australian Government whether the STC rebates you received extinguished your rights to sell any carbon offsets associated with your solar installation. 

Our primary objective is to ensure that no double-counting of carbon reductions occurs. We will keep you informed of any government rulings on this matter.

The Voluntary carbon market is where businesses and people buy credits to offset their own emissions (good will) and achieve carbon neutrality (eg. tree planting, renewable energy).

Credits are verified by organisations like Verra, Gold Standard and Aetium.

In 2024, electricity made up 45.8% of Australia’s emissions (440 Mt CO2-e). Solar is the fastest, most effective way to cut this.

4 million rooftop solar systems are cutting over 20 Mt of CO2 emissions each year. It’s like offsetting the carbon footprint of 1.2 million Australians*

*Every Australian represents 18.6 tonnes of CO2 per year.

Once you've registered and established your solar baseline, you can unlock even greater environmental benefits by optimising your system and habits.

System Performance:

• Clean panels periodically, check for shading from trees and debris
• Add monitoring to spot underperformance early
• Add panels or upgrade to high efficiency (400W+)
• Add battery storage (new Federal rebate) to ease grid pressure at peak times and cut demand when the sun isn’t shining.

Energy Consumption & Storage:

• Upgrade insulation, lighting and appliances to lower your reliance on grid electricity
• Pair with a full electric vehicle (EV)

Yes, you can register multiple solar systems on the same property. To prevent potential double counting, our platform registers your entire property location, identified as a street address or a parcel ID.

When you register them, you can aggregate the total number of solar panels across your standing systems. If they were installed in different years (eg. 2020 and 2022), simply use the midpoint as the installation year (eg. 2021).

The registration step is used to :

1. Start the clock for us to monitor your solar
2. Calculate a baseline estimate of your positive impact, that you can use to justify improvements (eg. system upgrade, battery storage..)

The critical step is the verification. After 12 months, we’ll check: 

1. The total clean electricity (kwh) generated by your systems, old and new combined
2. The battery presence (if any)

Only what is verified can be converted into tradable or retirable TCUs.

Yes, you can update your solar system or battery details without affecting the certification date of your project.

Updating Solar System

1. Click: https://app.aetium.com.au/account/projects (login required to access your project list)
2. Locate the Solar Project you wish to update
3. Click: Manage (Top left)
4. Click: Update solar system (Dropdown menu)
5. Enter New Solar details: Panels, Year, Orientation, Wattage, App
6. Click: Save

Adding or Updating Battery

You can also add a Battery storage (or update it) to an existing solar project:

1. Click: https://app.aetium.com.au/account/projects (login required to access your project list)
2. Locate the Solar Project you wish to update
3. Click: Manage (Top left corner)
4. Click: Add or Update Battery (Dropdown menu)
5. Enter Battery details: Brand, Model, Units
6. Click: Save

Confirmation

1. Your project details will be updated on your ticket: https://app.aetium.com.au/account/projects
2. If upgrading your Solar, you will receive a confirmation email with the updated digital certificate (Your project certificate’s expiry date will stay the same).

Unfortunately, we can’t include past electricity production, as Aetium verifies emissions reductions retrospectively over a 12-month period starting from the date your project is registered.

This ensures all projects follow the same baseline and verification process. Once registered, your system’s ongoing generation will be tracked and verified annually for eligible carbon credit claims.

We have no connection to Energy retailers, this is about the clean electricity you create, irrespective of what happens to it (use, store, feed back to the grid).

Your retailer pays you directly for the solar you export to the grid, that’s separate from Aetium’s program.

What Aetium does is measure and reward your emission reductions (the carbon you avoid by generating clean energy), which is different from your electricity payments. In short:

• Retailer: pays you for exported electricity (kWh)
• Aetium: rewards you for avoided CO2 emissions, every year (verified kWh are converted to tradable Tonne Carbon Units (TCU)

It’s free to join and your impact helps Australia’s transition to cleaner energy.

Yes, adding a battery to your solar system will help get more credits +10-20%. Here’s why:

• Your main carbon savings come from the solar panels, they generate clean electricity that replaces grid power.
• A battery helps store and use more of that clean power, especially at night, which means you rely less on the grid and waste less solar energy.

So, while the battery improves efficiency and self-consumption, the main benefit for credits comes from the higher market value of solar + battery storage projects.

You can add your battery from the Project page https://app.aetium.com.au/account/projects

Aetium can register only properties located within our current Atlas range (Longitude 112-160°).

As a result, solar systems on the following islands cannot yet be registered:

• Heard & McDonald Islands (73°)
• Cocos (Keeling) Islands (97°)
• Christmas Island (106°)
• Norfolk Island (168°)

However the following islands are eligible:

• Cartier Island (124°)
• Ashmore Reef (123°)

• Lihou Reef (152°)
• Coral sea Islands (157°)
• Lord Howe Island (159°)
